Hi there! It's me with my lecture questions again. I tried rewatching the lectures and going to a lab facilitator to ask but they were confused too so I have a few questions this time: 1. In the Ford-Fulkerson problem slide (slide 18) is it the case that it will just repeat the path {s, a, b, t} and {s, b, a, t} over and over again or is this just a worst case scenario. If not, why would it take that path instead of the shorter {s, a, t} and {s, b, t}. 2. For Edmonds-Karp (slide 21), could you explain what the "ladder" meant ? Is it because if we saturate u v, we can only use v u to release u v and it repeats over and over like the Ford-Fulkerson problem slide? (i.e. it keeps getting longer and longer because you now can't go through u but must go through v)? A diagram would help alot! 3. For cut flow (slide 26), how is it that sum V f(u, v) = 0? Thanks for the help for my previous questions, Gozz and Max, you have been really helpful for my understanding!
